(a) connection of the OCMFET with the PVDF capacitor for a temperature-sensing test with T > T_amb; (b) example of current variation (black curve) recorded in real time for increasing temperatures, monitored by an optical pyrometer (blue curve); (c) calibration curve as absolute current variation vs. temperature (each point averaged over five measurements); (d) connection of the OCMFET with the PVDF capacitor for a temperature-sensing test with T < T_amb; (e) example of current variation (black curve) recorded in real time for decreasing temperatures, monitored by an optical pyrometer (blue curve); (f) calibration curve as absolute current variation vs. temperature (each point averaged over five measurements).
